Abstract
The utility model relates to a rotor punching sheet which comprises a rotor punching sheet body; two groups of winding slots are arranged at the circular edge of the rotor punching sheet body symmetrically; baffles are arranged at the axle lines of the winding grooves and divide the winding grooves into left and right chambers; the walls of the winding grooves are arc edges; two main notches are arranged on two sections of arcs of the rotor punching sheet body in an axial symmetrical manner; four circular rotor punching sheet grooves are symmetrically arranged on two sides of each main notch, and the diameter of each circular rotor punching sheet groove is 4.2 mm. A punching module of the rotor punching sheet only needs to be changed, and the original assembling mode of a generator is not changed; and the rotor punching sheet can improve the efficiency of the generator, and during the long-term using process, the electromagnetic noise is small, the heating of the rotor punching sheet and copper consumption are less, the powerless consumption of the generator can be reduced, and the output efficiency of the generator can be improved.
Description
Technical field
The utility model belongs to technical field of motors, specifically, relates to a kind of generator amature punching.
Background technology
The rotor punching of generator generally adopts silicon steel sheet to process; Be provided with outline and be circular punching body; The round edge symmetry of this punching body has two groups of winding slots, cuts off outstanding formation of the bottom land at place, said winding slot axis, and this partition is divided into two chambers with said winding slot; The height of said partition is lower than the height of winding slot cell wall; Cutting off width is 1/4～1/5 of said winding slot Breadth Maximum, on the axis that cuts off, has mounting groove, and the notch of this mounting groove is positioned at and cuts off the top., some rotor punchings just form generator amature after being stacked; Just can in winding slot, twine motor windings, the cover cartridge screw is fixed on winding in the winding slot by gland with stationary gland on the mounting groove; Simultaneously; Be to guarantee the winding number of turns of winding in the winding slot, need to strengthen the space of winding slot, prior art comprises that the inwall to winding slot digs and cuts; Make the body width at winding slot cell wall root place locate 2～3 times of the body width, even sacrifice the width of rotor punching main body for the cell wall top.Rotor punching is the key components and parts in the generator, its material, interior round size, excircle dimension, flute profile size, flute profile what etc. the efficient of generator is had direct influence.
The utility model content
The purpose of the utility model is to provide rotor punching, and this rotor punching is used for generator, and in long-term use, electromagnetic noise is little, rotor punching generates heat and copper loss reduces, and reduces the idle energy consumption of generator, improves the delivery efficiency of generator.
For achieving the above object; The technical scheme of the utility model is: rotor punching, comprise the rotor punching body, and the round edge symmetry of this rotor punching body has two groups of winding slots; The place is provided with partition in said winding slot axis; This partition is divided into left and right two chambers with said winding slot, and said winding slot cell wall is the circular arc limit, and axial symmetry is provided with 2 major trough mouths on two sections arc sections on the said rotor punching body; The bilateral symmetry of each major trough mouth is provided with the rotor punching groove of 4 circles, and its diameter is 4.2mm.
Further, the line of symmetry through said two major trough mouths is provided with two circular holes.
Further, the angle of circle center line connecting is 10 ° in said adjacent two the rotor punching grooves, the center of circle of its winding section and rotor punching.
When adopting technique scheme; The utility model has the advantages that: said winding slot cell wall is the circular arc limit; The base of a said winding slot is provided with semicircle breach; Axial symmetry is provided with 2 major trough mouths on two sections arc sections on the said rotor punching body, and the bilateral symmetry of each major trough mouth is provided with the rotor punching groove of 4 circles, and its diameter is 4.2mm.Only need to change the diel of rotor punching, do not change original fit of generator; This rotor punching can improve the efficient of generator, and in long-term use, electromagnetic noise is little, rotor punching generates heat and copper loss reduces, and reduces the idle energy consumption of generator, improves the delivery efficiency of generator.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model rotor punching embodiment.
Embodiment
As shown in Figure 1, the utility model rotor punching comprises rotor punching body 1; The round edge symmetry of this rotor punching body 1 has two groups of winding slots 2, is provided with at place, said winding slot 2 axis and cuts off 3, and this partition 3 is divided into left and right two chambers with said winding slot 2; Said winding slot 2 cell walls are the circular arc limit; Axial symmetry is provided with 2 major trough mouths 5 on two sections arc sections on the said rotor punching body 1, and the bilateral symmetry of each major trough mouth 5 is provided with the rotor punching groove 6 of 4 circles, and its diameter is 4.2mm.Line of symmetry through said two major trough mouths 5 is provided with two circular holes 4.The angle of circle center line connecting is 10 ° in said adjacent two the rotor punching grooves 6, the center of circle of its winding section and rotor punching.
Above-described only is the preferred implementation of the utility model; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; These also should be regarded as the protection range of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.
